Headteacher Max Vlahakis said: “Our heartfelt condolences go to the family and friends of our dear friend and colleague and her partner.

“Clare was an employee of Alumwell Junior School for a number of years and was an extremely popular and hard-working member of our teaching team and she will be greatly missed by everyone who knew her and worked with her at the school.

“In view of the circumstances, we have arranged for educational psychologists to be available at the school over the coming days to support both staff and pupils as they come to grips with the shock and sadness of such terrible news.”

Flowers left at Miss Sly’s end-terrace home included a bouquet from a Year 2 pupil with the message: “Cannot believe you have gone. Thanks for everything you have done in class. God bless.”

A message for Mr Vassell, addressed to Dearest Decca, read: “I love you so much and life will not be the same without you. I promise to do anything I can for your Mum and kids.

“I know you cared about your family more than anything in this world! Love from Dionne xx”
